WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 255,032, dated March 14, 1882.

Application tiled August 4, 1881. (No model.)

thetdescription given below, when viewed in connection with the accompanying drawings wherein Figure l is a side view, and Fig. 2 is a top view, of my improved device. Fig. 3 is a cross section of the same onthe line .fr

My improved stretcher consists of a double crank, A, ot" dat metal, having itscentral por' tion, a, bent so as to stand in a plane lateral to that of the end portions,as illustrated, and

handles A at each end, a hollow windlass or winding shell, B, secured to saidV bent portion a, and a hemispherical or bell-shaped locking device, C, mounted on a central interior stein, c, inserted in the windlass B, and having slots c' in its edge to engage the rope I), which rope passes through the crank at slot, c2, in the` stem c. In this construction the stem cis free to slide inward or outward ,in the windlass B the slot c2 )rcventinn' ini l e terferenccby the rope with such movement; but thc outward movement is limited by the rope, so that the stem cannot become dctached.` At the same time, by passing the rope through said stem the locking device is made to rotate with the windlass and prevented rom independent rotation, being thus held tirm and stationary when the windlass is stationary.

The` operation of the device is as follows: The grappling devices with which the ropeis provided at each end, but which are not shown, as their presence will be understood, having been made fast to the fence-post and wire, the operator begins to wind,and as he proceeds he withdraws the windlass from off the stem ot' the locking device, so that the ceiling upon the windlass may continue'without interruption thereby until the fence-wire is brought to the proper tension. When this pointis reached the locking-bell is slipped upon the rope,which enters slots c upon each side, and thus said bell, in conjunction with that portion of the rope passing through the stem, prevents any unwinding.

The lockingbell maybe kept awayfrom the rope during the winding operation by pressing upon the end ofthe stem c,which projects through the crank.

Instead ot' using a single rope, two ropes, each secured to a branch ot' the crank., may be substituted, and in lieu of passing the rope through the stem c a stationary or metal stop attached to the crank may be used.

Instead of the locking-bell, a forked-ended lever may he employed.

My stretcher has great advantages in that it is very simple, light, and strong, and inasmuch as the rope is wound from both ends at the same ti1ne,it takes up the same amount of slack with one-halt1 the number of turns required with the ordinary stretcher.

The winding portion of the windlass is made of a shell. It is thus rendered light, and room is obtained for the other parts of the stretcher.

I am aware ot' the construction shown in patent to Edward M. Grandal, No. 217,200, and hence do not claim broadly a stretcher provided with a double crank; but as my crank does not slide longitudinally, and always remains in the same position relative to the axis ot' the drum, it possesses important advantages over Crandals construction.

I claim- 1. The fence stretcher consisting of the crank, the hollow windlass secured to the crank, a locking device mounted upon a stem inserted in the windlass and having a sliding movementtherein, and the rope passing through the ends ofthe crank and the stem of the locking device, substantially as specified.

t 2. In a fence-stretcher, a locking device adapted to engage with the rope, mounted upon a stem heldin the windlass, and secured so as to rotate therewith, in combination with the windlass and rope, substantially as specied.

3. In a tence-stretcher, a locking device secured to the windlass so as to rotate therewith, and movable toward and from thc rope and adapted to engage the same at both sides of the windlass at the same time, in combination with the windlass and rope, substantially as speeitied.

4. The fence-stretcherprovided with a nonsliding double crank, substantially as set forth.
